ObjectiveTo investigate the therapeutic effects of the Anemarrhenae Rhizoma water extract （AR） on Alzheimer's disease （AD） model rats and to explore its potential underlying mechanisms. MethodsMale rats were intraperitoneally injected with D-galactose （100 mg·kg^-1） for 42 days， and on day 14， 1 μL of β-amyloid （Aβ_25-35， 2 g·L^-1） solution was injected into the hippocampus. Rats were randomly divided into a model group， low-dose AR （0.6 g·kg^-1）， medium-dose AR （1.2 g·kg^-1）， high-dose AR （2.4 g·kg^-1）， and a positive control group （donepezil， 5 mg·kg^-1）. Healthy rats receiving only a hippocampal injection of 1 μL of sterile saline served as the sham-operated group. From day 21， rats in the treatment groups were administered the corresponding drugs by gavage once daily for 21 consecutive days， while the blank control and model groups received an equal volume of saline. Learning and memory abilities were assessed using the Morris water maze. Brain tissue damage was observed by hematoxylin and eosin （HE） staining， and neuronal apoptosis was evaluated by terminal deoxynucleotidyl transferase dUTP nick-end labeling （TUNEL） staining. Levels of interleukin-1β （IL-1β）， tumor necrosis factor-α （TNF-α）， and interleukin-10 （IL-10） in brain tissues were measured by enzyme-linked immunosorbent assay （ELISA）. BV2 microglial cells were co-cultured with Aβ_25-35 （40 μmol·L^-1） for 2 h， and cell viability was determined by the CCK-8 assay to screen the optimal concentration of AR-containing serum （S-AR）. Cells were divided into blank control， Aβ_25-35， S-AR， EX527 ［silent information regulator 1 （SIRT1） inhibitor］， and S-AR+EX527 groups. Immunofluorescence staining was used to detect the expression of CD16， CD206， and high-mobility group box 1 （HMGB1）. Western blot analysis was performed to measure the protein expression of CD16， inducible nitric oxide synthase （iNOS）， CD206， arginase （Arg）， and proteins related to the SIRT1/HMGB1/nuclear factor-κB （NF-κB） signaling pathway. ResultsIn vivo experiments showed that， compared with the sham-operated group， the model group exhibited reduced platform crossings and time spent in the target quadrant （P<0.01）， prolonged escape latency， increased hippocampal neuronal apoptosis （P<0.01）， and obvious hippocampal damage. The expression levels of IL-6， TNF-α， IL-10， CD16， and iNOS in brain tissues were significantly elevated （P<0.01）， while CD206 and Arg protein expression showed an increasing trend without statistical significance. Compared with the model group， all AR-treated groups significantly increased platform crossings and target quadrant time （P<0.05， P<0.01）， alleviated hippocampal damage， reduced escape latency and neuronal apoptosis， downregulated the expression of TNF-α， IL-6， CD16， and iNOS （P<0.05， P<0.01）， and upregulated the expression of IL-10， CD206 and Arg （P<0.05， P<0.01）. In vitro experiments demonstrated that， compared with the blank control group， the Aβ_25-35 group showed increased fluorescence intensity of CD206， CD16， and HMGB1， as well as elevated protein expression of iNOS and CD16 （P<0.01）， while CD206 and Arg protein expression exhibited an increasing trend without statistical significance. After S-AR intervention， CD206 fluorescence intensity and the protein expression of Arg and CD206 were significantly increased （P<0.01）， whereas the fluorescence intensity of CD16 and HMGB1 and the protein expression of iNOS and CD16 were significantly decreased （P<0.01）. These effects were reversed by EX527 （P<0.05， P<0.01）. Furthermore， compared with the blank control group， the Aβ_25-35 group showed significantly increased cytoplasmic HMGB1 expression and p-p65/p65 ratio （P<0.01）， along with significantly decreased SIRT1 and nuclear HMGB1 expression （P<0.01）. In contrast， the S-AR group exhibited opposite trends compared with the Aβ_25-35 group， and the regulatory effects of S-AR on these proteins were reversed by EX527 （P<0.01）. ConclusionAR exerts neuroprotective effects in AD model rats by regulating microglial polarization and alleviating neuroinflammation， potentially through modulation of the SIRT1/HMGB1/NF-κB signaling pathway.

Intravitreal anti-vascular endothelial growth factor(anti-VEGF)therapy has been widely used, but the variability in its therapeutic efficacy limits individualized treatment. In recent years, the application of artificial intelligence(AI)has opened up new avenues for personalized treatment response prediction, and its core branches include machine learning(ML)and deep learning(DL). This review systematically retrieved and analyzed 41 relevant studies published up to April 2025. Comprehensive analysis reveals that AI predictive models are evolving from forecasting single endpoints(such as visual acuity or central retinal thickness)to integrating multi-dimensional endpoints(encompassing anatomical, functional, and treatment demand parameters)and generating predictive imaging outputs. In terms of technical approaches, DL models(28 studies, accounting for 68.3%)dominate this field due to their robust image interpretation capabilities, while ML models(10 studies, 24.4%)retain significant value in the analysis of structured clinical data. Cross-disease comparisons indicate that research efforts are most concentrated on age-related macular degeneration(ARMD)and diabetic macular edema(DME), with shared conceptual frameworks for model construction, yet distinct anatomical and functional indicators are prioritized for each disease. Currently, the field confronts several key challenges, including insufficient prospective clinical validation, limited model interpretability(the “black box problem”), and a scarcity of high-quality multi-center datasets. Moving forward, it is imperative to advance real-world validation and develop explainable AI techniques to expedite the clinical translation of these predictive models.

Practice-oriented education is an important link in cultivating qualified builders and reliable successors of socialism， and it is particularly important for cultivating high-quality talents in traditional Chinese medicine （TCM）. Practice-oriented education is a vital part in improving college students’ ideological and political literacy， an important measure for TCM colleges and universities to promote the inheritance and innovation of TCM culture， and a significant pathway to cultivate high-quality TCM talents. The prominent issues of practice-oriented education in TCM colleges and universities are that the small ideological and political classroom is not closely integrated with the large classroom of society， the characteristics of TCM culture are not highlighted， and the current situation of practice-based construction does not match the needs of talent cultivation. Based on systematic thinking， the construction of a collaborative education of TCM culture and red culture should start from the following four aspects： cultural integration-cultivating ideological and political education and ideological and political theory courses of TCM culture； medical and educational collaboration-leveraging the synergistic educational effect of clinical practice； practice reinforcement-integrating the small classroom of ideological and political education into the big classroom of society； and “double innovation” promotion-creating an educational environment for innovation and entrepreneurship of TCM.

Objective To summarize and analyze the clinical efficacy of negative pressure suction bell in the treatment of young children (≤6 years) with pectus excavatum. Methods The relevant clinical medical records of the children with pectus excavatum who received negative pressure suction bell treatment in the Outpatient Department of Children’s Hospital of Chongqing Medical University from May 2019 to January 2023 were collected. The age, sex, type, severity, depth of depression, duration of use and prognosis of children with pectus excavatum were retrospectively analyzed. Results A total of 100 pediatric patients were ultimately included in the study, comprising 74 males and 26 females. The age distribution was 57 patients aged 0-3 years and 43 patients aged 3-6 years. All patients were prescribed and used a negative pressure suction device for at least 3 months, after which they returned to our department's outpatient clinic for follow-up. The treatment demonstrated clinical effectiveness in 99 patients, yielding an efficacy rate of 99.00%. The excellent/good rate was 52.00%, and the complication rate was 8.00%. After treatment, the Haller index and the depth of sternal depression were reduced compared with those before treatment (P<0.001), and there was no statistical difference in the effective rate and excellent/good rate between different genders, different ages, different types of pectus excavatum, or different severity (P＞0.05). Conclusion Negative pressure suction bell is safe and effective in the treatment of young children (≤6 years) with pectus excavatum, and the correction effect has nothing to do with gender, type and severity.

Objective To investigate the current situation and health effects of indoor microbial pollution in Xi'an, to analyze the purification effect of air purifiers on indoor microbial pollution, and to provide reference for improving the indoor environment. Methods Through stratified random sampling, 20 families from rural areas and 20 families from upwind and downwind urban areas respectively were selected from Xi'an. Data was collected by questionnaire surveys and on-site environmental sampling. Non-parametric analysis and correlation analysis were used for statistical analysis. Results Overall, the standard-exceeding rate of total count of bacteria was 5.00%. The medians of the total count of bacteria and fungi were 312.50 cfu/m3 and 260.00 cfu/m³, respectively. In terms of health effects, the correlation between rhinitis and cold with total bacterial count was statistically significant (P<0.05), with the correlation coefficients of 0.182 and 0.223, respectively. Purification effect of air purifiers on microbial pollution was statistically significant (P<0.05). After opening for 2 hours, the total numbers of bacteria and fungi decreased significantly. Conclusion The occurrence risk of colds and rhinitis is increased by indoor microbial pollution. Air purifiers have a certain effect on decreasing the total number of bacteria and fungi. It is recommended to use air purifiers with high CADR of particulate matter, double-layer filter and sterilization and dehumidification function, and replace the filters regularly to reduce indoor microbiological contamination.

By analyzing information such as the number of publications，authors，institutions and keywords in the literature on the integration of traditional Chinese medicine（TCM）culture into ideological and political education in the past 10 years，it was found that the overall number of publications showed an increasing trend. As the main research fronts，TCM colleges and universities had not yet formed teams in cooperation with other universities. The research hotspots were relatively concentrated，but the research horizons were not broad enough. It is suggested that in the future，policy should be taken as the guide to build a cross-regional interdisciplinary cooperation system，horizontally and vertically extend research subjects，innovate and construct diversified teaching models，continue to deeply explore and organically integrate ideological and political education elements，continuously improve the evaluation system of educational functions，and further enhance the timeliness of integrating traditional Chinese medicine culture into ideological and political education. So as to make greater contributions to cultivating talents in the new era and promoting the inheritance and innovation of TCM culture.

Objective To compare the analgesic efficacy of combined ultrasound-guided thoracic paravertebral block(TPVB)with patient-controlled intravenous analgesia(PCIA)versus simple PCIA after open partial hepatic resection.Methods A total of 120 patients undergoing elective open partial liver resection in our hospital from September 2020 to September 2022 were prospectively recru ited,and then randomly divided into the TPVB+PCIA group(Group A)and simple PCIA group(Group B),with 60 patients in each group.Finally,there were 112 patients meeting the criteria and completing statistical analysis.The patients in Group A underwent TPVB at T8～T9 in the left lateral position before anesthesia induction,with injection of 0.33％30 mL ropivacaine.The patients in Group B had no above treatment.Both groups were given PCIA analgesia pump after surgery.The main outcome measures were analgesia levels at 4,8,12,24 and 48 h after surgery and VAS pain scores at rest and activity.The secondary outcome measures included mean ventricular rate and mean arterial pressure during operation,time required for the first postoperative analgesia relief,number of patients for the first postoperative analgesia relief 48 h after the operation,time for the first postoperative ground exercise,time for postoperative anal exhaust,total number of postoperative hospital days,and incidence of postoperative adverse reactions.Results Compared with the patients of Group B,those of Group A had significantly lower scores of resting VAS and exercise VAS scores at 4,8,12 and 24 h after operation(P＜0.001),decreased mean heart rate and mean arterial blood pressure during operation(P＜0.01),less cumulative consumption of tramadol within 48 h(P=0.018),extended time for first postoperative analgesic need(P＜0.001),decreased average number of PCIA effective compressions and number of relief analgesia(P＜0.001),and advanced time of first ground movement and anal exhaust(P＜0.001).But,there were no significant differences in VAS scores at 48 h after surgery,total length of postoperative hospital stay and incidence of postoperative adverse reactions between the 2 groups.Conclusion Combined TPVB+PCIA shows better analgesic effect than simple PCIA for open partial hepatectomy,and it can obtain more stable intraoperative circulation and promote rapid postoperative recovery.
